Description Robb Gatica 2024-04-17 17:26:52 UTC 
In the Linux kernel, the following vulnerability has been resolved:

x86/mm: Disallow vsyscall page read for copy_from_kernel_nofault()

The Linux kernel CVE team has assigned CVE-2024-26906 to this issue.

Upstream advisory:
https://lore.kernel.org/linux-cve-announce/2024041746-CVE-2024-26906-bb35@gregkh/T
Comment 1 Robb Gatica 2024-04-17 17:27:27 UTC 
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2275636]
Comment 5 Alex 2024-06-09 16:19:45 UTC 
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-26906 is: CHECK	Maybe valid. Check manually. with impact LOW (that is an approximation based on flags READ INIT BPF  ; these flags parsed automatically based on patch data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
